Choosing the perfect shower gel probably isn't top of our beauty priority list.  In fact, we tend to just pick up whatever is 2-for-1 in Tesco. But  it turns out our body wash could be responsible for many of our biggest beauty calamities, including acne on the chest and back. We should be using a separate body wash after working out.  Coming into Winter, there's no prizes for guessing that we should be choosing a more moisturising formula. However, what we didn't know is that we should be using a separate anti-bacterial formula after a sweaty workout sesh, especially if you are acne-prone. Francesca Fusco, M.D., a medical and cosmetic dermatologist in New York, told Women's Health that it is imperative to combat acne-causing bacteria in the shower post-gym.   A mixture of bacteria and sweat can cause acne.  She said: “For gym showers only, I recommend antibacterial soaps, because let's face it, gyms can be sources of bacteria." However, she did emphasise that anti-bacterial formulas can be very drying, so after your gym shower, "moisturizing is a must.” There are plenty of bacteria-fighting formulas available, like the Cetaphil Gentle Cleansing Antibacterial Bar. One more thing to add to the shopping list. *sigh*.
